VersaMax Boring System<br />
Roughing Insert Holders<br />
.768-6.024” (19.5-153)<br />
Insert holders sold separately — 2 insert holders are required for<br />
Double Cutter Roughing Head.<br />
Patented rigid design interlocks the insert holders to support each<br />
other. Cutting pressures are balanced and transferred back through the<br />
serrations to boring head body.<br />
Designed to use industry standard inserts, giving you the ability to use the<br />
most current insert technology available.<br />
Dimensions given in inches (mm).<br />
Weight given in lbs (kg).<br />

Unique patented design<br />
applies cutting forces from<br />
one insert holder to the<br />
supporting surface of the<br />
other; locking the insert<br />
holders tighter into the<br />
ground serrations. This is<br />
why the <strong>Urma</strong> double cutter<br />
is the most rigid roughing<br />
head available.<br />
